MUSICAL HOOP.

Specification of Letters Patent.

Patented Mar. 12, 1918.

Application filed March 31, 1917. Serial No. 158,896.

To all whom it may concern:

Be it known that I, l\IAR'11N T. BRODERICK, a citizen of the United States, res ding at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Musical Hoops; and I do hereby declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved musical hoop; and, to this end, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings,

Figure 1 is a side elevation of the invention;

Fig. 2 is a fragmentary view in transverse section taken on the line 2-2 of Fig. 1, on an enlarged scale;

Fig. 3 is a fragmentary detail view, partly in section, taken on the line 33 of Fig. 1, on an enlarged scale; and

Fig. 4 is a detail view with some parts sectioned on the line 44 of Fig. 1, on an enlarged scale.

The improved musical hoop comprises a central disk 1, inner and outer rings 2 and 3, respectively, spokes 4 connecting said disk and rings and bells 5 attached to the inner ring 2. The disk 1, as shown, is cut from a single sheet of metal, with its edge portion folded upon itself. This disk 1 stifiens the inner ring 2 and is suitable for advertising purposes. The rings 2 and 3 are each formed from a single piece of relatively heavy wire and the spokes 4 are of channel form. Each spoke 4 is formed from a single sheet of metal and the flanges thereof are folded inward upon themselves. By folding the edge portion of the disk 1 and the flanges of the spokes 4, the same are materially stiffened and the exposed edges thereof are made smooth.

The inner ends of the spokes 4 are bifurcated to receive the peripheral portion of the disk 1 and the outer ends thereof are notched at 6 to receive the outer or tread ring 3. The bifurcations in the inner ends of the spokes 4 are formed by cutting away the webs and bending the flanges, as shown in Fig. 2. Apertures 7 are formed in the webs of the spokes l to receive the inner ring 2, which is inserted therethrough before the ends of the wire, from which said ring is formed, are connected. The joints in the rings 2 and 3 and between the spokes l, disk 1 and rings 2 and 3 are rigidly secured by welding or other suitable means.

Formed in the inner ring 2, are a multiplicity of grooves 8, which completely encircle the same. As shown, there are four spokes and two grooves 8 between each pair of said spokes but, it is, of course, understood that there may be any desired number of spokes and grooves. Attached to the inner ring 2, is a multiplicity of bells 5, as shown, of the sleigh bell type. These bells 5 are attached to the ring 2 by clips or metal straps 10, having their intermediate portions bent to encircle the ring 2 and seated in the grooves 8. The lugs of the bells 5 are inserted between the ends of the straps 10 and attached thereto by nutequipped bolts 11 passed through alined perforations in said lugs and straps. Obviously, the grooves 8 hold the straps 10, and hence, the bells 5 properly spaced on the ring 2, but, at the same time, permit the bells to swing bodily, during the rotation of the hoop, in planes that radiate from the axis of the hoop. The nut-equipped bolts 11 may be sufiiciently loose to permit the bells 5 to have a slight circumferential movement, with respect to the hoop, during their swiveled movement thereon.

From the above description, it is evident that during the rotation of the hoop, the bells 5 will make complete rotations on the ring 2, under the action of gravity, as well as slight circumferential movements, with respect to the hoop. These movements of the bells 5 will ring the same and produce a musical sound, which affords amusement for children. During the rolling of the hoop, the uneven surfaces over which it may pass will also cause the bells to ring.

The above described hoop, while simple and of comparatively small cost to manufacture, not only affords amusement for children, but also displays to good advantage any advertising matter which may be placed thereon.

What I claim is 1. A musical hoop comprising two connected concentric rings, and bells pivoted to the inner ring for complete rotary movements in planes that radiate from the axis of the hoop.

2. A musical hoop comprising a central disk, two concentric rings, .spokes connecting the disk and rings, and bells pivoted to the inner ring for movements in planes that radiate from the aXis of the hoop.

3. A musical hoop comprising a central disk, two concentric rings, spokes connecting the diskand outer ring and having apertures through which the inner ring is inserted, and bells attached to the inner ring.

4. A musical hoop comprising a central disk, two concentric rings, channel spokes having bifurcated inner ends in Which the peripheral portion of the disk is secured and having apertures in their webs through having bifurcated inner ends in which the peripheral portion of the disk is secured and having notched outer ends in which the outer ring; is secured, said spokes having in their webs apertures through which the inner ring is inserted, and bells attached to the inner ring.

6. A musical hoop comprising two connected concentric rings, the inner of said rings having a multiplicity of circumferential grooves, and bells swiveled in said. grooves for movements in planes that radiate from the axis of the hoop.

In testimony whereof, I afiiX my signature in presence oi two witnesses.
